Early on June 10th, 2021 there was a solar eclipse<\/a> for the northern portions of the globe. This was not a total, but annular (or “ring”) solar eclipse. Satellite instruments, such as NOAA’s<\/a> ABI<\/a> on GOES-16 (East) can monitor the shadow of the moon as it falls on the Earth. There are several recent examples from December 2020<\/a> (South America), June 2020<\/a> (southern Asia), December 2019<\/a> (central Pacific), July 2019<\/a> (southern hemisphere), January 2019<\/a> (Asia) and August 2017<\/a> (central US).<\/p>\n\n\n\n

GOES ABI<\/h2>\n\n\n\n

The shadow cast on the Earth could be seen from NOAA’s GOES-16 (East) ABI. This included both the visible and near-infrared spectral bands, and the ABI band 7 (at 3.9 micrometers). <\/p>\n\n\n\n

There are other similar loops are posted on many web pages, such as this one from UW\/SSEC<\/a>. This page is a collection of those links.<\/a> <\/p>\n\n\n\n

The shadow from the moon could also been seen from NOAA’s GOES-17 (West) ABI on June 10, 2021. <\/figcaption><\/figure>\n\n\n\n

While it’s subtle, the shadow could also be seen in Japan’s AHI<\/a>. <\/p>\n\n\n\n

HEO (highly elliptical orbit)<\/h2>\n\n\n\n

A satellite was recently launched by Russia into a highly elliptical orbit (Molniya<\/a>). The satellite (Arctica<\/a>) is in a commissioning phase, but some imagery from the 10-band imager <\/a>of the eclipse shadow was released. <\/p>\n\n\n\n
